WALL CONSTRUCTION.

Specification of Letters Patent.

Patented J une 20, 1922.

Application filed December 11, 1920. Strial No. 430,022.

accompanying drawing is a specification, like characters on the drawing representing like parts. v

' This invention relates to wall construction comprising two tiers of blocks of cement or other plastic substance which are arranged to form an air space between them, the blocks of the tiers being bound together by cement which fills aligned grooves inthe meeting faces of the blocks and the tiers being connected together by suitable tie members.

- One of the objects of the invention is to provide a wall construction of this type in which the different courses of blocks in each tier are connected solely by the cement binding filling the aligned grooves and another object of the invention is to provlde a wall construction having blocks of relatively simple formation. Other objects of the invention are to provide im roved wall construction having features w ich will be more fully hereinafter set forth.

In the drawings wherein I have illustrated aselected embodiment of the invention, Fig. 1 is a perspective view of a portion of a wall embodying my invention.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a perspective view of one of the blocks. 7

Fig. 4 is a section on the line 1-4; Fig. 5.

Fig. 5 is a section on the line 5-5 Fig. 4:.

My improved wall is-composed of blocks 1 of cement or cementitious substance which are laid up to form two tiers 3 that are separated from each other to form between them an air space 4.

Each block 1 is preferably shaped so'that it is thicker transversely at the ends and at its central part'as indicatedwat 6 and 7 and it is also formed with a longitudinally extending groove 8 in its top face and a similar groove 9 in its bottom face. Each block also has a vertical passage which communicates'with the grooves 8 and 9. There may be one or more such passages in each block,

4 and these passages may be located at different parts of the block. In the construction shown each block has a vertical passage 10 in the formof a groove in each end face,

and also another vertical passage in the form of a hole 12 which is situated in the thickened portion 7, both passages 10 and 12- communicating with both grooves 8 and 9.

Each block also has one or more transverse passages leading from its inner face into a vertical passage and which is for the purpose of receiving a tie member 14 or 16.

I have herein shown each block as having such a transverse tie-receiving passage 11 1n each end face and another transverse tierecelvlng passage 13 leading into the hole 8. The outer face 5 of each block will preferably be plain. Y

In building a wall of blocks having this construction said blocks are laid up in two tiers that are separated from each other as sh own in Figs. 1 and 2 and when each course of blocks is laid the grooves 9 in the bottom of said blocks will be in alignment with the grooves 8 in the top edges of the blocks beneath.

As each course is laid up the corresponding courses of the two tiers are tied together by tie members 14 which are laid in as many of the transverse passages as desired. These tie members are in the form of rods having their ends 15 bent at right angles to the body of the rods. -When the blocks of any course are being laid the tie members 15 will be placed in the ooves or passages 11 with the arms or. en s 15 of the tie rods occupying the vertical grooves 10 and when the blocks are positioned with their ends in abutting relation the tie members will be confined in the aligned grooves 10 and 11 thus operating to tie the tiers together.

In addition to these tie members 14: other similar tie members 16 may be used if desired for tying together the opposing blocks in the tiers midway of their length. These tie members 16 extend through the passages 13 and have their ends 17 occupying the holes 12. The passage 13- is of a suflicient size to receive the bent end 17 of the member 16. So that these tie members can be inserted by turning them into a horizontal position and passing the bent ends 17 thereof through the passages 13 and then swinging said tie members into a vertical position with the bent endsin the holes 12. The blocks of the various courses are laid up without mortar or cement and after any course has been laid then a grouting or thin cement will be poured into the vertical passages 12 and 10, such grouting flowing through these passages into the horizontal aligned grooves 8 and '9 and filling the latter. This. ing when set thoroughly binds the locks together and at the same tlme encloses the bent ends of the tie members that occupy the vertical passages-thus anchormg-saldtie members firmly into place. 1

In a wall embodying my invention the blocks of each tier are bound together solely by the cement or grouting which is poured into the vertical passages thus obviating the necessity of using a trowel in laying up the wall. Furthermore the two tiers are connected together solely by metallic tie members thus making it impossible for moisture to work from one tier to the other across; theair space. Y i v I claim: p Y A wall construction comprising two tiers of superposed blocks each block having a outmeagre groove in both its top face and its bottom tie member being bent into a position at right angles to the body thereof and occupying a vertical passage.

In testimony whereo name to this specification.
